The cycle regression gate still read payload.moves, which schema v4
removed in favour of recording.instructions, so every game reported
replay_history_mismatch:0/N and games_with_issues tripped the
--require-zero-issues gate on master (runs 587/594/596).
Verified locally: 12-game gate run reports 0 issues.
